Application' led- July 28,

My invention relates to pumps.. It is the Object of my invention toprovidea' pump in vwhich the source of 4motive* power canv continuouslyoperate ina 'given' /direction producing reciprocation ot the pump partswithout the necessity ot reducing gears5-levers or Otlierapparatus.

It is a further object to provide a pump` which will takeup the minimumof floor space, which cair run at the speed of the motive pfwer andwhich willy be automatic In its operation'.v

This sleeve 6 has connected toit bypins V110@ a shiftingv sleeve 11lprovided with jaws 12 in which the shifting jaw 13 is fitted; This`sleeve 14 on a reciprocating shifting rod 15 guided in the eyes 16 ofthe casing 2. f y Y The clutch operating sleeve 11 is adapte-d toreciprocate upon the sleeve 6 as wellas rotate with it. Mounted in thesleeve 6 a split coll the respective sides of the collar adjacent thesplit'20` therein7 s uclr arl'ns being pivoted 0n thepins 21. The pin`10 is adapted to move between the upper ends oit the arms to draw thearms together or expand-'them tofopen' This collar surrounds a solid ornon-split sleeve 22 which 'is adapted to engage with theiexternalsurfaces of the threads oi the screw 23 to which screw it is splined bythe spline 24 in the groove 25. f 'i 7 Adjacent this screw is a nut andsleeve i ntegrally formed, the nut portion'being designated 26 and thesleeve being' designatedv27. This nut rests on a plate 28 supported bybolts 29on a collar 3() which is anv integral ar 17 having arms 18 and19 connected to part of the casing2. -Ttturns in abeari'ng 31 Y inthiscollar 30.1 Surroundingthe sleeve27 is the upper `frictiondragmember 32 adapted to rictionally resist the vrotation oi the sleeve27 and the nut 26 asthe nut 261s'internally threaded to receivethe screwThis sleeve extendslupwardly to the bottom ot' the collar 22. On thesleeve -is` a`-second split clutch collar33. 'This collar has a mentr ofarms designated34 and 35actuated by the pin 36 and supported on pins'37on The shifting rod l5 isv prov-idedwi'tli an` upper notch 38' and'lowernotch 40 engaged by a` spring pressed plunger 41 actuated by thespring-42 located within the casing 2.-

At the bottom of lfriction dragl 43 is providedy having an arm 44engaging with the stationary rod 45 which also holds the upper frictiondraginposition. A shifter member 46i's carried onthesucker rod 47adapted to engage with through; the spring 49 on l' the, Thereis alsoprovided on Ythe shifter rodansimilar arrange- 9 thecollar' 48l lshifter rod, f y,

other collar 5() and a spring 5l. The .screw is connected to the rod insuch a manner that it is entirely independent oit the rod in itsrotation first in one direction and then in the other, but is soconnected to the rod that the rod and screw reciprocate together. Thusthe rotation of the screw first in one direction and then in the otherin the arms t3 will not affect the sucker rod 47 but the movement ot thescrew up and down will move the rod.

The base casting 1 carries the tube 52. It carries at the bottom thereotaV pump cylinf der and thestrainer 54: together with the valvesgenerally designated 55 and 5G ot anyf .les-aired character.

The base casting is providedl with an exit pi ageway 57 through whichHuid passes beneath the valve 5 8 to the outlet pipe 59; An air chamber(30 is provided with the usual Lincumatic switch 6l having electricalconnections 62 in circuit with the motor $5.

life/571,00]- of Operatiowffhe motor rotates continuously in agivendirection, such asa clockwise direction atsome desirable speed,such as i750V revolutions per minute. As it rotates, it rotates thesleeve (3 and the clutch sleeve ll. It the parts are as in ,Figure 3with the shitting rod 15 in its uppermost position fthe arms l9and 18are spread apart at the top and drawn together at the bottom clampingthe split sleeve 17 on the sleeve 2&2 splined toV the worm 23 therehyrotatingl the screw ineving it downwardly.

At this time the upper 'friction drag 82 tric#` tionally engages thesleeve 27 preventing it Yfrom rotating and preventing its associated nut2G from rotating.

The clutch sleeve 331s now open. The continued movement of the worm willoperate through the shifter arm t6 and rod 15 to bring about a. downwardmovement oi Vthe rod, positioning the plunger lll in the notch 38 whichwill Vresult in the relative shitting Vdownward ol" the sleeve '1l onthey rotating sleeve @releasing the upperclutch.and closin g the lowerclutch or split sleeve 33 on the sleeve Q7 V'ausing the sleeve 27 andits'nut 26150 rotate withV the sleeve 6, and, in doing so, to reversethe direction ol `movement ot the screw 23 working the screw upwardly.`VThe lower drag t3 holds the screw 'from turning.

The rotation oit the sleeve (i and the sleeve 27 is, oit course,alifected through the .clutch action of the split sleeve 33.

Thus, in my apparatus, the essentials consist ot a continuously rotatingmotive power unit, driving a continuously rotating driv Ving member witha driven member,4 which reciprocates and rotates in opposite directions,

V4and an automatic means tor joining the rocations as may he necessaryto adapt it to varyingconditions and uses. i

Having thus 'fully described my invention, what l claim as new anddesire to secure by Letters Patent, is
